About EC Technology

 

EC (Electronically Commuted or Controlled) motors are electric motors that use permanent magnets on the rotor and electronic controls to regulate voltage and current. They have no brushes, eliminating sparking and extending motor life. By electronically controlling the stator and avoiding energy losses from inducing the rotor field, EC motors provide better performance, improved controllability, and cooler operation compared to traditional induction motors.

      Advantages:

  • High efficiency, even at part load, reducing energy consumption and operating costs
  • Runs cooler, minimizing waste heat and extending component life
  • Wider operating range, allowing one motor to replace multiple models
  • Built-in electronic control for precise speed and performance adjustment
  • Quieter operation compared to traditional motors
  • Longer lifespan with reduced maintenance requirements

EC Fan Grid 

A highly efficient and energy-saving multiple fan array for HVAC Retrofit and New Air Handling Unit (AHU) applications.

 

Equipped with easy-to-control EC Motor technology (ECM), Rosenberg’s ECFanGrid improves reliability, flexibility, and simplicity in existing or new ventilation systems.

Compared to traditional single blowers, the ECFanGrid reduces space requirements by up to 50% while delivering uniform airflow distribution that improves the performance of downstream components such as coils and filters.

Air Curtains

An air curtain is a fan-powered device that creates an invisible high-velocity air barrier over a doorway or entrance.

 

This air barrier efficiently separates two different environments without limiting the access of people or vehicles.

 

An air curtain can help to reduce heating and cooling costs by up to 80% while protecting the indoor environment, and increasing personal comfort.

Uno Box

An assembly consisting of a backward curved impeller EC fan mounted inside a sturdy box. It is Rosenberg’s approach to the modular construction of a grid as a stand-alone unit, or in a case when a previous casing no longer exists.

 

Constructed out of an extruded aluminum frame with thermally and sound insulated galvanized steel panels. Powered by energy-efficient and easy to control EC motors (ECM).

 

They can be stacked in a grid of any configuration. Simple and clean. Plug and Play.
